| Abstract: | Ice flood monitoring is very important for preventing river ice disaster.We use HJ-1A and HJ-1B CCD data to monitor ice flood of Yellow River and propose a decision tree method to extract river ice.The experimental results show that HJ-1A and HJ-1B are suitable for river ice identification.HJ-1A/1B CCD data has great potential in ice flood monitoring of Yellow River. |
